Aviation
12z issuance...VFR conditions and light north winds prevail
through the forecast period. 49

Prev discussion issued 424 am cst Thu jan 18 2018
near term now through Thursday night ... Cool and dry weather
continues through the near term as a zonal flow pattern sets up
aloft and surface high pressure builds east into the region. With
winds (and thus, cold air advection) weakening, we begin to see a
slight warming trend today as temperatures reach the mid 40's
across the area. Hopefully this will help melt and evaporate the
remaining icy spots on roads. Tonight, clear skies and calm winds
will result in plenty of radiative cooling, allowing temperatures
to become very cold once again. The previous hard freeze watch
has been upgraded to a hard freeze warning for areas generally
north of i-10 late tonight, where lows will dip into the upper
teens to around 20 degrees. Closer to the coast, temperatures will
get down into the low to mid 20s. 49
short term Friday through Saturday night ... A 1028 mb surface
high pressure centered across the forecast area will move east
over the western atlantic, but a trailing surface ridge will
remain across the southeast states and northeast gulf of mexico
through Saturday night. A light and variable wind through Friday
night will become southeasterly on Saturday along the western
periphery of the surface ridge, bringing increasing low level
moisture and the potential of patchy fog late Saturday night.

Zonal upper flow will become southwesterly as an upper shortwave
over the southern plains moves slowly east, however rain-free
conditions should remain through the short term.

Temperatures will continue to trend warmer through the period,
with highs Friday climbing to between 52 to 56 degrees, and highs
Saturday climbing to between 60 to 65 degrees. Lows will trend
above normal by Saturday night. 22
long term Sunday through Wednesday ... An upper level low
pressure area exiting the southern rockies early Sunday will
move east over the central great plains through Sunday night, and
toward the great lakes region on Monday. The surface high pressure
ridge across the southeast states and northeast gulf of mexico
will weaken early next week as surface low pressure area
developing across the western high plains deepens and lifts
northeast toward the great lakes through Tuesday morning. An
associated cold front will approach the region from the west on
Monday.

These features will bring widespread rain back to the region late
Sunday night through early Monday evening, along with possible
embedded isolated thunderstorms. Widespread rainfall amounts
around one-half inch should occur, with locally higher amounts
near one inch possible. Patchy to areas of fog should resume early
next week ahead of the cold front. Dry conditions will follow
through mid week. 22
marine... Moderate offshore flow gradually diminishes through
today, with a generally light easterly flow settling in Friday
and Saturday. Periods of slightly stronger drainage winds will be
possible near the shore over the next few nights, at least until a
better established southeast flow develops Saturday night into
Sunday. Onshore flow then continues into Monday before the next
cold front blasts through and winds shift back to northerly Monday
night into the middle part of next week. Seas diminish to around
1 to 2 feet into this weekend before gradually increasing to 3 to
5 feet early next week in response to the increasing winds. 49

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
